0303 numbers are the sister range to 0300 numbers and are identical in every way, except for the prefix.
Recently released by Ofcom 0303 numbers are exclusively for the public and charity sector. They come complete with an online telephone control system that will save you time and money and help make you more efficient.
Unlike 08 type numbers 0303 numbers cost your callers no more to call than any normal landline number (e.g. 01/02), even from a mobile phone. Therefore they have the public’s trust and your callers will be completely confident when phoning you.
With your Inclusive Package you get 1000 inbound minutes. You then pay 1p per minute if you go over your 1000 minutes. Alternatively you may also upgrade to Package 2, 3, 4 for more minutes.
